Th1 cells

Th1 cells are a type of immune cell that help defend your body against infections, particularly bacteria and viruses. They are part of the immune system's adaptive response, meaning they learn to recognize specific pathogens. Th1 cells release chemicals called cytokines that activate other immune cells, like macrophages, to attack and destroy invading microbes. They also support the activation of certain immune responses important for clearing infections. Overall, Th1 cells play a critical role in coordinating the body's targeted immune defense, especially in fighting intracellular pathogens that hide inside our cells.
